Abstract

PURPOSE: To enable inspection even if inspection pit water is contaminated by gaseous fixed fission products by adding a cooling water cleaning device for supplying cleaned cooling water into a fuel leakage inspection device.
CONSTITUTION: The inspection pit water itself previusly lifted by from a piping 16 by using water pump 13 is cleaned in a cleaning piping 12 in the cleaning device before the fuel leakage inspection. A fuel assembly 3 to be inspected is then inserted into the fuel leakage inspection device 2 and thereafter, the gas of a gas pressurizing vessel 7 is pressurized to form a free liquid surface 6 in the inspection device 2 to isolate the same from the ambient. The water previously cleaned by the cleaning device 11 is injected through a piping 15 into the inspection device 2 by starting a water pump 14 so that the water in the device is substd. with the cleaned water. A gas pump 9 is driven, after this substitution, to transfer the gaseous fission products in the water into the circulating gas which is subjected to a continuous measurement in a gas analysis instrument 8. The leakage inspection is thus enabled even if the inspection pit water is contaminated by the gaseous fission products as a result of fuel leakage.
